Prediction with two fixed-effects - large number of IDs
I have no direct experience with such horrific models, but your formula is a mess and Google suggests the biglm package with ffdf.
Specifically, you should convert your discrete variables to factors before you build the model, particularly since you want to use predict after the fact, for which you will need a new data set with the exact same levels in the factors.
Also, your use of I() is

Adding Two-Headed Arrow in map legend
Hello Jim,
Thanks again. I am getting the two-headed arrow but I cannot seem to get
the coordinates right for the arrow to appear beneath the map. These
coordinates puts the arrow on the left hand side. Thanks again!
Sincerely,
Milu

how to read numeric vector as factors using read.table.ffdf
I have a big data set that includes character variables of many different
values. I'm trying to use ff to read the data and then use biglm.big.matrix
to build linear models. However, since big.matrix will convert all
character vectors to factors and the character labels will be lost. I
decided to create a lookup table outside of R for my character columns and
use numbers to represent different

Adding Two-Headed Arrow in map legend
Dear David,
The device was the issue. The quartz() device works fine but pdf() does
not. Now I just need to figure out the limits for map for Europe. Thanks
for all your help and patience.

Adding Two-Headed Arrow in map legend
Hi Milu,
My fault here. As I don't have the data to make the map and try out my
suggestions I mixed up the x and y coordinates. Try this:
par(xpd=TRUE)
arrows(-19.75966,53,33.60000,53,code=3)
par(xpd=FALSE)

Thanks again! I do want the arrows at the bottom (beneath the map). This is

Bilateral matrix
or in base R : ?xtabs ??
as in:
xtabs(~previous_location + current_location,data=x)
(You can convert the 0s to NA's if you like)
Cheers,

xtabs does this automatically if your cross classifying variables are
factors with levels all the cities (sorted, if you like):

> y <- sample(letters[1:5],8,rep=TRUE)
> xtabs(~ x + y)

b 0 0 1
c 1 0 0
d 1 1 1
e 1 1 0

Hi Milu,
There is a two-headed arrow on the image you sent, and it seems to be
where you specified. Did you want it beneath the map, as:
par(xpd=TRUE)
arrows(-22,54.75,-22,74,code=3)
par(xpd=FALSE)

Hi Milu,
I just realized that by "the bottom of the map" you may mean "beneath
the map", in which case you should use:
par(xpd=TRUE)
arrows(...)
par(xpd=FALSE)
